  • Patent number: 8607615
    Abstract: A two-dimensional gas chromatography system having first and second separation columns, a thermal modulator disposed between the first and second columns and having a plurality of stage channels, and a micro heater monolithically integrated in the thermal modulator. The thermal modulator is operable to trap and focus gas/vapor species within the plurality of stage channels upon cooling and release the gas/vapor species to the second column upon heating by the micro heater.
    Type: Grant
    Filed: October 18, 2010
    Date of Patent: December 17, 2013
    Assignee: The Regents of The University of Michigan
    Inventors: Sung Jin Kim, Katsuo Kurabayashi, Kensall D. Wise, Edward T. Zellers, Bruce P. Block

  • Patent number: 7293449
    Abstract: A thermal modulator device for gas chromatography and associated methods. The thermal modulator device includes a recirculating fluid cooling member, an electrically conductive capillary in direct thermal contact with the cooling member, and a power supply electrically coupled to the capillary and operable for controlled resistive heating of the capillary. The capillary can include more than one separate thermally modulated sections.
